2 Claims.

This invention relates to supporting brackets for guide tracks for sliding doors of containers and the method of making such brackets.

One object of the invention is to provide a one piece bracket of the character indicated of rugged design, formed by simple bending operations.

A further object of the invention is to provide a one piece bracket for supporting the guide track for a sliding door of a container, comprising a securing section fixed to the container and having upwardly and outwardly extending arms on the outer ends of which the guide track is fixed, supporting the track at an elevation above the securing section of said bracket, the arms being formed integral with said securing section.

A still further object of the invention is to provide a bracket as set forth in the preceding paragraph formed from a flat steel bar of rectangular cross section and of greater width than thickness, by simple bending operations, to provide the securing section and upwardly inclined arms extending therefrom.

Another object of the invention is to provide a .one piece supporting bracket formed from a flat steel bar by simple bending operations, com-prising a securing section, outwardly and upwardly inclined arms extending from opposite ends of the securing section, right angular, fiat track supporting sections at the outer ends of the inclined arms, and inwardly directed, horizontal the side wall, and a portion of the guide track for the door, illustrating my improvements in connection therewith. Figure 2 is a vertical sectional view, corresponding substantially to the line 22 of Figure 1. Figure 3 is a broken view,

similar to Figure l, with the horizontal bracing arms for the track omitted. .Figure 4 is a plan view of a flat steel bar or blank from which my improved bracket is formed. Figure 5 is a horizontal sectional view, corresponding substantially to the line 55 of Figure 3. Figure 6 is a view,

similar to Figure '1, illustrating another embodiment of the invention. Figure '7 is a horizontal sectional view, corresponding substantially to the line 1-! of Figure 8. Figure 8 is a transverse,

vertical sectional view, corresponding substan- 2 tially to the line 88 of Figure 6. Figure 9 is a plan view of a flat steel bar from which the improved bracket shown in Figures 6, '7, and 8 is formed.

In said drawings, I0 indicates the side s ll of a car, which side sill forms a continuation of the usual side wall ll of the car. The side wall II is provided with the usual opening closed by a sliding door of well-known design, not shown, and the track for supporting the door for sliding movement is indicated by l2. It is the usual practice to provide an angle bar fixed to the side sill of the car for supporting the side wall Hr An angle bar of this character is shown in the drawing, the same being indicated by 13. A portion of the usual sliding carrier on which the door is supported is shown in Figure 2, the same being indicated by M. I

In carrying out my invention, referring first to the embodiment illustrated in Figures 1 to 5 inclusive, I provide a one piece bracket A for supporting the track l2. This bracket is formed from the blank 15, shown in Figure 4, by simple bending operations. The blank I5 is preferably in the form of a flat steel bar of rectangular cross section and of greater width than thickness.

The bracket A comprises a horizontally extending central flat section l-B secured to the outer side of the side sill 10, a pair of laterally spaced, upwardly inclined arms Illl extending from opposite ends of the section I6 and formed integral therewith, and angularly extending securing sections l8-. I8 at the outer ends of the arms l.6l6 to which the track i2 is fixed. The

5 bracket A is preferably riveted to the side sill iii of the car although it may be welded in place. As shown, rivets l9l9|9 engaged through suitable openings in the section I5 of the bracket and the side sill are employed for this purpose. The track I2 is held in place on the bracket by rivets 2-0-20 engaged through suitable openings in the track and sections Iii-l8.

As shown in Figure 2, horizontal braces in the form of separate bars 24-2! may be added to give a more firm support to the track. These bars, as shown, have angularly bent securing sections 22 and 23 at the outer and inner ends thereof respectively fixed to the outer side of the track and the vertical web of the angle bar It. When such bracing bars are used, they are preferably so placed that the rivets 28-20 of the bracket A may be employed to secure the same to the track.

Informing the one piece bracket A from the 3 steel bar blank [5, shown in Figure 4, the bar i bent outwardly along the diagonal lines a-a and a-a at substantially right angles, thereby forming the securing section It; and the arms 11-". The upper edge of the blank shown in Figure 4 corresponds to the upper edge of the sections of the finished bracket, and the portions of the blank from which the securing section 16, arms I1-l1, and angular sections 3-18 are formed are indicated respectively by H8, H1-ll1, and H8-ll8. The diagonal lines of bending a-a and a-a diverge towards said upper edge of the blank, thereby causing the arms l1-l1 to incline upwardly when the bends have been made. The angular sections [8-18 of the bracket at the outer ends of the arms I1-l1 are formed by bending the end sections 8-! I8 of the blank backwardly at right angles with respect to the sections l l1-l l1 along the diagonal lines 17-1) and 17-!) which also diverge upwardly, the inclinations of these lines being such that the sections l8-I8 of the bracket extend horizontally and parallel to the securing section 15. The described bends to form the finished bracket A may be made in succession or the whole blank may be .bent to finished form in one stamping operation. The perforations for the rivets l9-l9-l9 and 20-20 in the sections 16 and l8-I8 of the bracket A are preferably made before the bending operations are performed on the blank I5, the perforations for the rivets l9-l9-I8 being indicated by 24-24-24 and those for the rivets 20-20 being indicated by 25-25 in Figure 4.

Referring next to the embodiment of the invention illustrated in Figures 6 to 9 inclusive, the construction of the bracket, which is indicated by B, is the same as that of the bracket A hereinbefore described, with the exception that a pair of horizontal bracing arms are added, which extend rearwardly from the guide track for the sliding door.

The bracket B shown in Figures 6, 7, and 8 is formed from the blank 23 shown in Figure 9, which is in the form of a flat steel bar of rectangular, transverse cross section. 26 is of considerably greater length than the blank l5. 7

The bracket B includes a, horizontally disposed, central flat section 21, laterally spaced, upwardly inclined arms 28-28 extending from opposite ends of the section 21 and formed integral therewith, angularly extending, securing sections .29-29 at the outer ends of the arms 28-28, and

horizontally disposed bracing arms 30-30 extending inwardly from the outer ends of the sections 29-29 and forming integral continuations of said last named sections. The inner ends of the arms 38-30 are bent at right angles and extend laterally from said arms to provide securing flanges 3l-3i. The section 21 is secured to the outer side of the side sill of the car, which side sill is indicated by 32, rivets 33-33-33 which extend through suitable openings in said section and in the web of the sill being employed for this purpose. The guide track for the sliding door is similar to the track I 2 hereinbefore described and is indicated by 35. The track 35 is fixed to the bracket B by rivets 36-38 extending through suitable openings in the sections29-29 and the track 35 and the angular securing flanges 31-3! are fixed to the outer side of the vertical web of the angle bar 31, which corresponds to the angle bar I3 hereinbefore described, by rivets 38-33 extending through suitable openings in The blank 4 said flanges, the web of the angle bar 31, and the web of the sill 32.

In forming the one piece bracket B from the steel bar blank 26, the bar is bent outwardly along diagonal lines 0-0 and 0-1: at substantially right angles, thereby forming the securing section 21 and the arms 28-28. The upper edge of the blank shown in'Figure 9 corresponds to the upper edges of the difl'erent sections of the finished bracket B and the portions of the blank from which the section 21, arms 28-28, angular sections 29-29, arms 30-30, and flanges 3l-3I are formed are indicated respectively by I21, l28-l28, 129-129, l30-I30, and l3l-l3l.

The diagonal lines of bending 0-0 and 0-0 diverge toward the upper edge of the blank, thereby causing the arms 28-28 to incline upwardly when these bends have been made. The angular securing sections 29-20 at the outer ends of the arms 28-28 are formed by bending the sections 129-129of the blank on the diagonal lines 11-01 and d-d at right angles to the sections 28-I28 and rearwardly with respect to said sections, as viewed in Figure 9. The diagonal lines of bending d-d and d-d diverge upwardly, as shown, thereby bringing the sections 29-29 of the bracket to a horizontal position, parallel to the section 21. In forming the bracing arms 30-30, the sections I30-l30 of the blank are bent backwardly with respect to the sections l29-I29 along the straight vertical lines f-f and f-f at right angles to said sections, thereby disposing the arms 30-30 in horizontal position, parallel to the arms 28-28. To form the securing flanges 3l-3l, the end sections l3l-I3l of the blank 20 are bent forwardly at right angles to the sections'I30-I30 of the blank, as viewed in Figure 9, on the vertical lines g-g and g-g. The bends of the blank 26 in forming the bracket B may be either made in succession or the whole blank may be bent to finished form in one stamping operation.

The perforations for the rivets 33-33-33, 36-36, and 38-38 in the sections 21, 29-29, and 3l-3l, respectively, are preferably made before the bending operations are performed on the blank 28, the perforations for the rivets 33-33-33, 36-35, and 38-38 being indicated by 39-39-39, 40-40, and 4l-4l, respectively in Figure 9.
